Many religions want to claim that their beliefs are older and they influenced others, but there is no proof that Christians or the Hebrews borrowed from Zoroastrianism. That bbc article doesn't provide any proof. They just claim that Zorastrianism is older (there is no proof that it's older than the OT religion) therefore the jews got the belief from them. Zoroaster was supposedly born during the time of the Babylonian captivity. It's more likely he got his beliefs from the Jews (prophecies of the Christ predate the Babylonian captivity). We do have proof of faith. We have scripture, the prophets, and Christ himself. To say there is no hell is calling Christ a liar. Christ spoke many times about hell.
